A grad school friend and her husband, both PhDs, just shared on Facebook that they lost their life savings to a scam. They finally saved up enough to buy a house in the DC area. The scammer inserted itself in between them and the title company, and basically provided fake account info for them to send the down payment to. They are working with the FBI, but the money is likely just gone. Absolutely horrible. They said all the documentation from the scammer looked perfect - coming from the right email address, right fonts and format, perfect English, etc.
I would certainly have never thought to call the title company directly on a verified number to confirm the transfer details - but you bet your *** I will the next time.
